Functional Description

IS230TRLYH1E is a Relay Output Assembly Board developed by GE. The Solid-State Relay Output terminal board is a specialized 12-output relay board designed to control external devices through solid-state relays. Unlike mechanical relays, these solid-state relays offer enhanced durability and are certified for use in Class 1 Division 2 hazardous environments, making them suitable for industrial applications where safety and reliability are paramount.

Features

• Features 12 isolated output relays, each providing isolated voltage feedback on all circuits. This isolation ensures that each output operates independently, which enhances safety and reliability in critical systems.
• The use of solid-state relays instead of mechanical relays offers several benefits, including faster switching times, longer operational life, and the ability to operate in hazardous environments. These relays are particularly useful in applications where frequent switching and low maintenance are required.
• The solid-state relays allow the TRLYH1E to be certified for use in Class 1 Division 2 environments, which are areas where flammable gases, vapors, or liquids may be present under abnormal conditions.
• Unlike mechanical relay boards that offer form-C (SPDT) contacts, the TRLYH1E provides 12 Normally Open (NO) contacts. This configuration is ideal for applications where the relay should only connect the circuit when activated.
• The board does not distribute solenoid power. Instead, external power must be provided by the user to power the solenoids connected to the relay outputs.

Installation

• Wiring Connections: The terminal board features a terminal block with 24 terminals, which can accommodate wires up to #12 AWG. Each solenoid should be connected directly to the I/O terminal block. The dc relays on the board are unidirectional, so it is important to ensure correct polarity when connecting the load to these relays.
• Grounding: A shield terminal strip is attached to the chassis ground and is located next to each terminal block. Proper grounding is essential to ensure safety and minimize electrical noise.

Operation

• During power-up, all relays remain de-energized until they are connected to the control system. The relays have a built-in failsafe feature, which de-energizes the relay if a cable is unplugged or if communication with the associated I/O processor is lost. This feature is critical for maintaining safe operations in the event of a system failure.
• In simplex operation, control signals and relay output voltage feedback signals are transmitted between the I/O processor and the board through the JA1 connector. For Triple Modular Redundancy (TMR) applications, control signals from the three I/O processors (R, S, T) are fanned into the board through connectors JR1, JS1, and JT1. These signals are voted upon, and the result controls the corresponding relay driver. The relay drivers receive power from all three I/O processors, which is shared via diodes to ensure redundancy.
• External power must be supplied for the solenoids connected to the relay outputs. The TRLYH1E does not provide this power internally.

Frequently Asked Questions

What is IS230TRLYH1E?
It is a Relay Output Assembly Board developed by GE

What happens if the solenoid excitation voltage drops below the specified level?
The solenoid excitation voltage is monitored downstream of the fuses. If the voltage falls below 12 V DC, an alarm is triggered and latched, indicating a potential issue with the solenoid power supply.

What is a composite diagnostics alarm, and when does it occur?
A composite diagnostics alarm, identified as L3DIAG xxxx, occurs when any of the outputs on the terminal board goes unhealthy. This alarm provides a general indication that there is a fault or issue with one or more outputs.

How does the system handle hardware incompatibility faults?
Hardware incompatibility faults are created when there is a mismatch detected by the I/O processor when reading the ID chip of the terminal board or its connectors. The ID chip contains essential information such as the board serial number, type, revision number, and connector locations (JR1/JS1/JT1). A mismatch in this data triggers a fault to alert users of a potential hardware issue.
